Using MATLAB, and assuming operation the GPS L1 band at 1575.42 MHz, determine the polarization (linear elliptical, circular) of the following at the plane z = 0 a) E= 10 sine (wt - Bz)ax + 10 cos(wt - Bz)ay V/m b) E= 2cos (wt - Bz)ax+ sin(wt - Bz)ay V/m c) E= sin(wt - Bz)ax 2 cos (wt - Bz)ay V/m - d) E= cos(wt - Bz+3π/5)a+ 1.5 cos(wt- ßz + 3x/5)ay V/m c) E₁ = el(8²-) ax + j8 e-zay V/m Fe [Note: You must convert this to the instantaneous form first! You can use MATLAB.] To accomplish this, I recommend using the function: "comet (x_axis,y_axis)". Look at the lecture slides to determine what the x_axis and y_axis should be. The function will perform an animation generating a plot similar to that done in the slides. At the end of the animation, copy the figure and attach it to your answer sheet. Note that the x-axis and y-axis of the comet function may not be equal, so what is circular may appear to the eye as being elliptical. To solve this, run the following command after the animation ends. grid on axis equal You time axis 't' should cover a full period (but not much more than that). And the time step should be fine enough to sample the period appropriately. If you take too many points the animation will be slow, on the other hand, if you take too little you won't be able to see a clear animation.
